What is Backup Retention?

Backup retention defines the window of time during which you can restore your website to a previous state. It is separate from backup frequency: a host can run daily backups but only keep 3 copies, meaning your restore window is 3 days — not the full month you might assume.

Why retention is the number that matters

Frequency tells you how often a snapshot is taken. Retention tells you how far back you can actually go. If a hack, corrupted deployment, or bad plugin update silently damages your site and you don't notice for two weeks, a 7-day retention window means every stored backup already contains the damage — and you have nothing clean to restore from.

The silent-corruption problem

This is the most underappreciated backup risk: threats that activate or are discovered long after the initial breach. Ransomware that sits dormant for 30 days before encrypting files. A WordPress plugin update that slowly corrupts the database. A developer who pushes broken code that only surfaces in an edge case. In each scenario, short retention windows leave you with no usable backup.

What to ask your host

Ask specifically: how many restore points do you keep, and how far back does the oldest one go? "Daily backups" tells you nothing about retention. A host advertising "daily automated backups" may only keep the last 1 or 3 copies — enough for accidental deletion, not enough for delayed-discovery incidents.
